神经科学是一个神经科学.
视觉感知视觉感知视觉感知

背景情况:

突出的分心器捕捉注意力可能会损害视觉搜索.
之前的研究经常使用相同奇心度的刺激,可能忽视了奇心度的作用.

研究的目的:

调查相对目标和分心器异常如何影响注意力捕获.
确定异心差异是否会调节突出的干扰因素和相关目标之间的竞争.

主要方法:

参与者在同质的非目标中执行了对形状定义的目标的视觉搜索任务.
目标和分散器的奇特度在近,中和远的水平上被独立操纵.
记录了手动反应时间和眼睛的运动,以测量注意力捕捉.

主要成果:

干扰器的存在显著减缓了搜索性能.
手动搜索捕获不受目标分散器异心差异的影响.
眼运动捕捉显示了对更接近固定点的刺激的偏差.
奇心效应似乎是附加的,表明独立的空间调制.

结论:

注意力捕捉是由异常度调节的,特别是在眼睛运动中.
对分心刺激的手动和眼运动反应之间存在分离.
离心率作为一个独立的空间因素,影响着注意力选择.

Eccentric Loading

Eccentric Loading

Eccentric loading is a crucial concept in the study of structural engineering and mechanics, particularly when analyzing the stability and stress distribution in columns. Unlike centric loading, where the force is applied along the centroidal axis, causing uniform compression, eccentric loading occurs when a force is applied off-center. This off-center application introduces not only direct compressive stress but also bending stress, significantly influencing the column's behavior under...

The Anchoring-and-Adjustment Heuristic

The Anchoring-and-Adjustment Heuristic

In order to make good decisions, we use our knowledge and our reasoning. Often, this knowledge and reasoning is sound and solid. However, sometimes, we are swayed by biases or by others manipulating a situation. For example, let’s say you and three friends wanted to rent a house and had a combined target budget of $1,600. The realtor shows you only very run-down houses for $1,600 and then shows you a very nice house for $2,000. Might you ask each person to pay more in rent to get the...
